Abstract

Present work was carried out in the Department of LPM, FVSc and AH (SKUAST- Kashmir) to assess the change in values of minerals like Nitrogen, Phosphorus and Potassium due to Lactic Acid and Yeast Fermentation of poultry waste under the temperate climate of Kashmir Valley. Poultry waste in the form of dead birds and litter manure was used for this study. Nine groups with four replicates each were formulated as: G1: Dead birds; Poultry litter, G2: Dead birds; Litter manure; LB @1.0 per cent G3: Dead birds; Litter manure; LB @0.5 per cent G4: Dead birds; Litter manure; Yeast @1.0 per cent G5: Dead birds; Litter manure; Yeast @0.5 per cent G6: Dead birds; Litter manure; LB@ 1 per cent; Yeast @ 0.5 per cent G7: Dead birds; Litter manure; LB @ 1 per cent; Yeast @ 1per cent G8: Dead birds; Litter manure; LB @ 0.5 per cent; Yeast @ 0.5 per cent T9: Dead birds; Litter manure; LB @ 0.5per cent; Yeast @1per cent. At final stage of work it was recorded significantly highest (P0.05) nitrogen level of 18.2 g/kg during winter and highest nitrogen level of 17.8 g/Kg during summer in G2 group (LB@ 1%). In the final product of fermentation significantly highest (P0.05) highest phosphorus level of 0.85 g/Kg in G7 (in which LB@ 1% and Yeast@ 1% was added) during winter season and the significantly (P0.05) highest P level of 0.85 g/Kg in G5 and G6during summer season was observed. Similarly significantly (P0.05) highest potassium level observed in the final product of fermentation was 7.0 g/Kg in G7 (in which LB@ 1% and Yeast@ 1% was added) during winter season and significantly (P0.05) highest K level of 8.0 g/Kg in G3 group (in which LB@ 0.5% was added) during summer season was observed. There was a significant increase in the nitrogen, phosphorus and potassium level in the final product of lactic acid and yeast fermentation of poultry waste.
